You are forgetting the utility. A $2500 computer in 1992 without internet, GUI etc would be as hard sell as ML-1. As utility of the product increases, the $2500 price tag starts making sense. The biggest issue with AR is that we haven't found the killer application yet. It's not the form factor or field of view (we have had large computers with pathetic displays), it's the utility to a common consumer beyond few minutes of amusement.
